Existence of positive solutions for -Laplacian problems.
Infinitely many weak solutions for a non-homogeneous Neumann problem in Orlicz--Sobolev spaces
Under a suitable oscillatory behavior either at infinity or at zero of the nonlinear term, the existence of infinitely many weak solutions for a non-homogeneous Neumann problem, in an appropriate Orlicz--Sobolev setting, is proved. The technical approach is based on variational methods.
